• GND (3): Short for ‘ground’. There are several GND pins on the Arduino, any of
which can be used to ground your circuit.
• 5 V (4) and 12 V (5): As you might guess, the 5 V pin supplies 5 V of power, and
the 12 V pin supplies 12 V of power. Most of the simple components used with
the Arduino run happily off 5 or 12 V.
• Analog (6): The area of pins under the ‘Analog In’ labels (A0 through A5 on the
UNO) is Analog In pins. These pins can read the signal from an analog sensor
(like a temperature sensor) and convert it into a digital value that we can read.
• Digital (7): Across from the analog pins are the digital pins (0 through 13 on the
UNO). These pins can be used for both digital input (like telling if a button is
pushed) and digital output (like powering an LED).
2.6 GSM Module
GSM module used to send SMS to the corresponding person mobile number. Module
has a unique identity number similar like mobile IMEI. It can use the range of
900/1800 MHz bands for the purpose of communication. The inbuilt interface allows
serial communication from a microcontroller like Arduino.
2.7 Arduino
Arduino software is the best re-enactment and most prominent in view of accessibility
of all microcontrollers within it. So, it is easily programmable and can be understood
the programme very simply. And, modification to the programme done at an ease.
Here is the important setup in software.
3 Working
The whole mechanism will be activated/triggered with the support of high gas concentration or flame detection or abnormal temperature rises above the threshold. With
the aid from analog/digital gas sensors coated with the most sensitive layer SnO 2 , the
gas above the threshold level is detected. The sensor MQ-6 is well suited for detection
of gases like iso butane, liquefied petroleum gas (LPG) as well as some important
hydrocarbons. The sensor with the heater activates the layer of Sno 2 for detection. It
then gives analog voltage as output to the Arduino and which with the help of ADC
of microcontroller reads the signal. And then the analog output converted to digital
output, which used as an external stimulus to initialise or activate the whole system.
The concentration of the gas/smoke will be detected by analog digital converter of the
Arduino. Microcontroller Arduino reads the values of the gas/smoke concentration
